- the fiber optic cable 20 transfers light to the distal tip 14.
- the handle 12 is attached to the distal tip 14 by means of a slot 34 in the proximal end 28 of the distal tip 14, as shown in FIG. 2, fitting into grooves 40 near the top of the handle 12.
- a set screw is inserted into a threaded hole (not shown) approximately one-half inch from the top of the handle 12 at a 20 degree angle from the outer surface of the handle 12. When the set screw is tightened it engages the outer wall of the distal tip 14.
- the length of the handle 12 including a light source guide fitting 22 is approximately 4.723 inches.
- the handle 24 is made of aluminum having a knurled surface for a positive grip when in use.
- the aluminum may be embodied by Type 2024 manufactured by Admiral Metals, of Woburn, Mass., U.S.A.
- the fiber optic cable may be embodied by type N.A. 0.66-0.68, size 0.0015 inches, core 89%, and clad 11%, manufactured by Electro Fiber Optics, of Marlborough, Mass., U.S.A.
- the distal tip 14 body is made from delrin which may be obtained from AIN Plastics of Norwood, Mass., U.S.A.
- the distal tip 14 is typically 4 inches in length. It has an outside diameter at the proximal end 28 of 0.8 inches and at the distal extremity 30 the outside diameter is typically 0.341 inches.
- the lens 24 is placed into an opening provided in a lens mounting support holder 32 and a cylindrical retainer 36 is positioned against the perimeter of the lens 24 and glued in place.
- the distal tip 14 comprises a viewing lens 24 with an anti-reflection coating and may be a single or multiple-element lens arranged at the proximal end 28 of the distal tip 14.
- FIG. 1 shows a single viewing lens 24 having a 110 mm focal distance and an outside maximum diameter of 0.689 inches.
- the lens 24 in the present embodiment has a 2.5 ⁇ magnification. However, magnifications ranging from 2 ⁇ to 50 ⁇ may be employed in other embodiments contemplated.
- the lens may be embodied by glass type BK-7, manufactured by Schott, of Duryea, Pa., U.S.A.
- the lens 24 has a radius first surface of 56.85 mm, a radius second surface plano, and a center thickness of 4.0 mm.
- the lens coating comprises a conventional single-layer MgFl for visual wavelength and may be embodied by type AR-100, manufactured by Precision Optics Corporation, of Gardner, Mass., U.S.A.
- the viewing lens 24 is configured so that the eye 16 of a visual observer may see the region at or near distal extremity 30 of the distal tip 14 even by locating the observer's eye 16 a fair distance (such as 1" to 10" typical) behind the proximal lens 24.
- the fiber optic cable 20 terminates at an opening 38 at the top of the handle 12, as shown in FIG. 3, which is positioned adjacent to the lens 24, and light is emitted from the polished end of the fiber optic cable 20 at an angle conforming with the slope of the lens 24 resulting in negligible backscatter.
- the distal tip 14 includes an access means 26, such as one or more openings in the wall of the distal tip 14, to allow the insertion of hypodermic needles to perform injections.
- An access means 26 is shown in the cross-section view in the FIG. 1, but in the preferred embodiment there are three access means 26 spaced 120 degrees around the perimeter of the distal tip 14.
- the access means 26 allows a straight needle to be inserted into the distal tip 26 and guided to the distal extremity 30 to accomplish therapeutic treatment.
- the insertion of the needle into the distal tip 14 access means 26 may be observed in reasonable focus so that the medical visualization device 10 may be used as an aid to the application of a therapeutic substance.
- the medical visualization device 10 provides for visualizing an anatomical area through a body orifice such as ear, nose, mouth, vagina, urethra, rectum, etc. in order to perform medical examination for diagnosis or enables local therapeutic treatment by application of therapeutic drugs or other agents to local parts of the body.
- a body orifice such as ear, nose, mouth, vagina, urethra, rectum, etc.
- the medical visualization device 10 may, with proper lens assembly and mechanical interface at the proximal end 28 of the distal tip 14, be used to allow visualization by electronic means such as video camera, telemedicine sensor and the like which then electronically provides an image to an observer, such as viewing on a video monitor.
- another embodiment of the distal tip 14 may be employed without a lens 24 in the proximal end 28.
- the length of the distal tip 14 is typically 4 inches and the diameter of the proximal end 28 is 0.8 inches.
- the distal tip 14 is sized at an outside diameter of the distal extremity 30 of no greater than standard medical catheter sizing of "26 French" (0.341 inches or 8.7 mm) to allow insertion into the urethra to allow the distal extremity 30 (25 mm or less from the proximal opening of the urethra) to be in contact or close proximity to the urethral sphincter, controlling urine flow from the bladder.
- Side access means 26 or ports in the distal tip 14 allow access to the sphincter for injection of "bulking agents” (such as collagen compounds, vulcanized silicone, etc.) to fill out the slackened sphincter muscles.
- This device 10 provides about 2.5 ⁇ magnification, and a doctor may view the sphincter with his eye very close or 8 to 10 inches or more distant from the Medical Visualization Device 10.
- This embodiment may incorporate a reasonable cost, disposable distal tip 14 and a re-usable, sterilizable (even by autoclave), fiber optic handle 12. The fact that the end of the fiber optic cable 20 of handle 12 is located behind the lens 24 of the distal tip 14 and outside any apparent requirement for a "sterile field", may not require sterilization of the handle 12. Further, this embodiment enables the doctor, being shielded from the bladder and sphincter, to complete diagnostic and therapeutic operations with minimum interference from urine discharge.
- the distal tip 14 may be embodied without a lens 24 thereby providing for direct view of an anatomical area of a body.
- another embodiment of this device 10 accepts curved needles whereas the present embodiment is for straight needles. Therefore, it is the intent of the appended claims to cover all such variations and modifications as come within the true spirit and scope of this invention.
